GAS-PRODUCER.

, SPECIFICATION forming part of Letters Patent No. 428,237, dated May20, 1890.

Application filed August 9, 1889. Serial No. 320,224:- (No model.)'

To all whom, it may concern:

Be it known that I, lVILLIAM J. TAYLOR, a citizen of theUnited States,residing at Chester, in the county of Morris and State of New Jersey,have invented certain new and useful Improvements in Gas-Producers, ofwhich the following is a specification.

My invention relates to certain improvements in the construction of agas-producer shown and described in the Letters Patent No. 399,7 98granted and issued to me under date of March 19, 1889. The gas-producerof said patent, among others issued to me of even date therewith, is forcarrying out a method of making gas, which consists in placing and thenmaintaining a deep bed of ashin a chamber beneath a bed of incandescentfuel and introducing a blast of air or steam, or both,

through the ash and fuel, and the means em ployed for maintaining saiddeep bed of ash consists of a revolving table located beneath saidash-chamber and above an ash-pit, and arranged to permit grinding anddischarging of the non-combustible material supported on said table overthe periphery thereof.

The principal object of my present invention is to construct agas-producer so that the operation of grinding and discharging the ashor other non-combustible material may be observed and more thoroughlyeffected.

A further object of my invention is to provide simple and efficientmeans for correcting any irregularity in the grinding of the producerdue to the formation of clinker, by which the bed of ash or othernon-combustible material may sink faster at one point than at another,or otherwise become abnormal.

A further object of my invention is to provide simple and effectivemeans whereby the angle of repose of the ash on the table may be alteredwithout either raising the table or lowering the ash-hopper.

My invention consists, in a gas-producer, first, of a main casing, thelower portion of which is provided with observation-openings fitted withdoors and an ash-hopper forming the wall of an ash-chamber suspended orotherwise supported beneath a combustion-chamber, and provided withholes to enable the grinding operation to be observed, and bars to beinserted through said openings of the main casing and holes of theash-hopper to break up clinker or to agitate the non-co1nbustiblematerial in its passage downward through said hopper; second, a tablecapable of being rotated and adjustable gates depending or otherwisesupported from the lower portion of said ash-hopper, whereby thedischarge of ash or other non-combustible material may be governed orprevented at the point or place desired, and, third, a supported tablecapable of rotation and adapted to receive brackets or hooks forsupporting a segmental band or ring to permit of a change being made inthe angle of repose of the ash by simply varying the width or height ofthe segmental band or ring, thereby obviating the necessity of loweringsaid ash-hopper or of raisingsaid table. 7 y i The nature of myinvention will -be more fully understood from the following description,taken in connection with the accompanying drawing, which illustrates,partly in ver tical central section and partly in elevation, agas-producer of my improved construction embodying the characteristicfeatures of my invention.

Referring to the drawing, A is the metallic main casing with a flangedtop plate B, constructed and arranged to form a receptacle forcontaining a supply of water.

0 is the ash-pit, provided with observation openings 0', fitted withdoors and in the wall of said pit are provided apertures c for thereception of agitating-bars c and also an ash-pit door 0 D is thebrick'foundation, provided with a horizontal conduit (1' and a suitableelbow (1 E is a feed-hopper fitting over the ringb of the top plate B.

c is a bell for closing the hopper, operated in any preferred manner.

F is the gas off-take, fitted to the rim 1) of the top plate B,or thegas may be discharged from the producer through the horizontal offtakeF.

In the top plate B is provided one or more sight-openings b with coversI), for ascertaining the condition of the fuel in the producer.

G is the combustion-chamber of fire-brick or other preferred material,and preferably constructed bosh shape at both the top and bottom.

g is a chamber between the main casing A and the inner casing of thechamber G for the reception of loam, ash, or other suitable material toallow for expansion.

9 is a series of tubes arranged around the wall of and extending throughthe main casing A and the inner casing of the chamber G for permittingof an examination of the illcandescent fuel in the combustion-chamber.These peep-holes are provided with plugs 9 II is an ash-hopper, thewalls of which are provided with perforations 71, through which bars maybe inserted to break up clinker or other non combustible material, andalso I provided with T-shaped catches or hooks h,

tached at the base to an angle-bar (Z embedded in the foundation D, andat the top to the casing A. The ash-hopper H is riveted or rests upon anangle-bar c, or otherwise suspended or supported beneath the fire-brickcasing of the chamber G.

I is asteam or air blast inlet-pipe fitted into the brick foundation andcommunicating with a conduit d.

J is a sleeve, with a flange or plate j formed, preferably, integraltherewith. This sleeve is heldin position by means of bolts j, passingthrough the flange j and the base-plate d. A pipe K, having a flange 70,formed, preferably, integral therewith, fits into the sleeve J and restsupon the upper edge thereof.

L is a circular table having a rim Z around its periphery and providedwith hooks or catches Z, secured to the peripheral portion of the tableand projecting therefrom. table L is secured by means of the bolts Z tothe flange of the pipe K.

M is a pipe provided with a flange m and with one or moredeflecting-hoods m held above the pipe M by means of bars m Thesedeflecting-hoods have openings in the tops thereof, and above the upperone is a cap m held in position by means of a bar m The pipe M isfastened to the table L by means of bolts m.

N is a shaft extendingacross the ash-chamber O and supported in bearings01 in the sleeve J, and also in the casing of the ash-pit C. To thisshaft is secured a cog-wl1ee1n which meshes with the rack Z of thetable, and near the end thereof is a gear-wheel 713, which meshes with asmaller gear-wheel 92, mounted on a short horizontal shaft 51;, 8X=tending through the casing of the ash-pit C. To the opposite extremityof the shaft w is The mounted a crank 19 for actuating said gear-,

wheels, and thereby imparting a rotary motion to the table L. 1

O is a segmental metallic ring or band held in position between theflange of the table L and the hooks or catches Z.

The mode of operation of the gas-producer hereinabove described is asfollows: The fuel is fed into the combustion-chamber G through thefeed-hopper E by lowering the hell 6, and the bell is then drawn upwardsnugly against the throat of the hopper. Air or steam and air are forcedor otherwise admitted through the pipe I, conduit (1, and pipes K and M,and discharged into and through the bed of ash and fuel in the chamber Gfor efiecting combustion. The gas produced from the combustion of thefuel is conducted off through either the off-take pipe F or F for use.

When necessary during the time the producer is making gas to remove ashor other non-combustible matter, the table L may be revolved, and therequisite quantity of ash or other non-combustible material accumulatingin the combustion-chamber G may be readily discharged over the peripheryof the table into the ash-pit 0 without specially in terfering with themaking of the gas, and, moreover, the grinding operation may be observedby opening the doors c and the clinker or other non-combustible materialmay be broken or agitated by inserting bars through the openings 0' inthe wall of the ash-pit and the apertures c of the ash-hopper II.

The discharge of the accumulating ash or other non-combustable materialover the pe riphery of the table L may be diminished or entirelyarrested at any point by lowering the gates 7L2 and the angle of reposeof the ash or other non-combustible material may be altered by theinsertion of the bands or rings 0 between the rim of the table and thehooks or catches Z.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is-

1. In a gas-producer provided with a main shell having a series ofobservation-doors in the lower part thereof, a perforated ash-hopperforming the wall of an ash-chamber and providedwith gates, anash-supporting table located below said hopper, and means for revolvingsaid table, substantially as and for the purposes set forth.

2. In a gas-producer, the combination, with a bosh-shaped ash-hopperprovided with sliding gates, of an ash-supporting table locatedimmediately below said hopper and means for revolving the same,substantially as and for the purposes set forth.

3. In a gas-producer, the combination, with a perforated ash-hopperhaving adjustable gates extending from the lower part thereof, of an ashsupporting table located immediately below said hopper, means forrevolving said table, hooks supported by said table,

and a segmental ring or bar held by said and adapted to receive a rim orring, substantially as and for the purposes set forth.

6. In a gas-producer, the combination, with a perforated ash-hopperprovided with adj ustable gates, of an ash-supporting table, means forrevolving the same, and a vertical blastpipe extending upward throughsaid table, substantially as and for the purposes set forth.

In Witness whereof I have hereunto set my signature in the presence oftwo subscribing witnesses.
